PARIS (AP) — French police have opened their criminal investigation into whether topless photos of Prince William's wife Kate — which appeared in an edition of the French Closer magazine — were an invasion of privacy.

A French court ordered police to obtain information on Closer magazine employees after the British royal couple filed the criminal complaint Monday.

Marie-Christine Daubigney, assistant prosecutor for the Nanterre court, outside Paris, told The Associated Press on Wednesday that she has instructed police to get the names of some Closer employees, including the journalist who wrote the article.
